If you are using Visual Studio Code and you want to add a new project to your workspace, the easiest thing to do is something like –
dotnet new xunit -f netcoreapp2.1
But you may get an error –
Error: Invalid parameter(s):
-f netcoreapp2.1
'netcoreapp2.1' is not a valid value for -f (Framework)
Here’s how to solve it.
Run –
dotnet --info
You will get a list of installed frameworks, your list will be different than mine –
This will show the list of frameworks installed .NET Core SDKs installed: 2.1.202 [C:\Program Files\dotnet\sdk] 2.1.402 [C:\Program Files\dotnet\sdk] 2.1.503 [C:\Program Files\dotnet\sdk] 2.2.203 [C:\Program Files\dotnet\sdk]
Choose a version of the framework that you want, in my case I’ll use 2.1.503
Run this –
dotnet new globaljson --sdk-version 2.1.503
Now run –
dotnet new xunit -f netcoreapp2.1
and the new project will be created.
